There are six basic types of simple machines, starting with the inclined plane.

简单机器有六种基本类型，先从斜面开始介绍。

The massive ball rolls slowly down the inclined plane.

1. 沿着斜面缓慢滚动。

Alberto got up and put the inclined plane away again.

阿尔贝托起身，又把斜面收了起来。

" Are the planets marbles on an inclined plane then" ?

“那么行星是在倾斜平面上弹珠吗”？

" This is called an inclined plane, " he said.

“这叫做斜面，”他说。

He stood bowed over the inclined plane with the marble again.

他再次弯下腰站在有理石斜面上。

So we will have described a trajectory corresponding to the marble's path across the inclined plane.

因此，我们将描述与弹珠穿过倾斜平面路径相对应轨迹。

Thus the wheels come from one part of the factory and are rolled on an inclined plane to a particular spot.

因此，车轮来自工厂一， 并在一倾斜平面上滚动到一特定位置。

No misunderstanding. I've learned what that request actually means, and I don't want to be joined to another object by an inclined plane wrapped helically around an axis.

我没误会 我了解到那要求意味着什么 我不想变成一斜面绕轴螺旋状转上几圈之后样子。

Like inclined planes, pulleys are used to gain a mechanical advantage: objects are easier to lift using a pulley system than by using your own two hands.

和斜面一样，使用滑轮是为了获得机械优势：使用滑轮系统比使用你自己双手更容易举起物体。

An inclined plane can be pretty much any object — a ramp, a slide, or even just a block of wood — as long as it consists of a sloping surface.

斜面几乎可以是任何物体——斜坡、滑梯，甚至只是一块木头——只要它由一倾斜表面组成。

Helpful when you're trying to lift heavy objects, the inclined plane offers a mechanical advantage: the force required to move an object up the incline is less than the weight being lifted.

当你想要举起重物时，斜面可以提供机械优势：将物体沿斜面向上推所需力小于直接举起物体重量。
